PADI Enriched Air Diver Exam |Question and Answer|
100% Correct
what is the primary benefit of diving with enriched air? - ANSWER it exposes you to
less nitrogen and let's you dive longer
What is enriched air? - ANSWER Enriched air is any nitrogen/oxygen gas blend
with more than 21% oxygen.
Enriched air ____________ the no stop limits compared to air - ANSWER Extends
when diving with enriched air nitro, for a given depth you should expect narcosis to
be _______________ compared to diving with air. - ANSWER the same as
True or false: it is to simplistic to say enriched air is safer than air when well within air
no stop limits because enriched air creates an oxygen hazard and the DCI rate is
already very low and recreational air diving. - ANSWER True
Advantaged of using a dive computer with enriched air nitro include that.... -
ANSWER it adds multilevel diving advantages for the longest no stop dive time,
most models will warn you if you exceed the maximum depth for your gas blend, and
simplifies dive planning
The general recommendation for scuba equipment (other than your cylinder) used
with enriched air is... - ANSWER everything can be used normally just as it is with
air up unless using a blend of more than 40% O2

should have a standard visual inspection sticker, the cylinder should have a contents
sticker, and the cylinder should have a sticker to indicate whether it's oxygen service
rated.
Nitro requires a dedicated cylinder because... - ANSWER it's important no one
accidentally confuse it with an air cylinder - it can be hazardous to unknowingly dive
with enriched air, and it can be hazardous to blend enriched air in a conventional air
cylinder
